The Terrifying Hollow Face Illusion (Video)

Stephen Fry and the panelists on the BBC show QI are struck by the strange motions of the inverted face of Albert Einstein demonstrating the Hollow Face Illusion, and a little side-variation of the illusion.

We’ve told you about the Hollow Face Illusion before. This illusion involves a sculpted face, but instead of the usual convex human face of a sculpture, the sculpture is flipped and we’re shown the inside of the face. In this case, it looks like Einstein stuck his face in some molten plastic and we’re looking at the impression.
